The main feature of the crystal structure is the inter-molecular N - H?O hydrogen bond, which links mol-ecules into zigzag chains along the a axis. These chains are further stacked along the b axis. The crystal structure features non-classical inter-molecular C - H?O inter-actions. The crystal studied was a nonmerohedral twin, with a twin ratio of 0.505 (1):0.495 (1).Article
